Electron spin resonance spectra of ferricinium salts

Abstract

The e.s.r. spectra of three ferricinium salts, prepared under specified conditions, were recorded at 77 K for crystals, powders and glasses in dichloromethane and water. Numerical values of g‖ and g⊥ were calculated and compared with those of carboranes and of species prepared by γ-ray irradiation of ferrocene.
